Well characteristics

Across the wells Glenn Martell & Son Inc. has drilled, the median depth is 140 ft (middle half 113 ft–230 ft), median tested yield 14 gpm, and median static water level 25 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1972–1987" refers to the earliest and latest well logs attributed to this company in the DWR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
